Application filed Ianuary'21, 1927'. Serial No. 1625511 Thisinvention'relates to container caps and its primary object is to providea sealing cap including means whereby the cap can be easily andexpeditiously removed from its container with very little effort on thepart of the'operator. I a

A further object of the invention is to provide a bottle cap includingan opening attachment therefor adapted for removing the cap from thebottle without the use of tools or the like. i

Another object of the invention is to provide a bottle cap including anopening attachment therefor, that is extremely simple in construction,contains few parts and is inexpensive to manufacture.

This invention also consists in certain other features of constructionand in the combination and arrangement ofthe several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which: I

Figure 1 is a vertical sectional view taken through the neck of thebottle and showing my novel cap secured thereto with the openingattachment arranged in normal position.

Figure 2 is a similar view showing the opening attachment disposed tooperative position and the manner in which it removes the cap.

Figure 3 is a top plan view of my cap and attachment per se.

Referring to the drawings in detail the letter A indicates the neck of abottle which is provided with the usual grooved head B for receiving acap, and in the'present instance the cap includes the usual crimpedflange 1 adapted to be received in said groove as best shown inFigure 1. The top 2 of the cap is provided with a centrally disposedopening 3 adapted to receive my novel opening attachment which isprovided with a body of substantially right angle configuration with ahook 4 formed on the arm 5 thereof while the arm 6 terminates in a thumbpiece 7 with a projection 8 extending therefrom at its juncture with thethumb piece 7. The projection 8 provides a shoulder; for engagement withthe flange 1 as shown in Figure 1 of the drawings, for retaining theattachment in its normal posi tion. The hook 4 is provided with arounded bight portion 9 and is arranged in the opening 3 for engagementwith a disk plate 10 having aconcavity 11 thereinto accommodate the hookin the manner as shown in Figure 1, but when the thumb piece 7 isactuated and the attachment is moved to the position as shown in Figure2, it will be obvious that such movement will cause the end of the hookto engage the cap 2 and remove the same from the bottle and by providingthe rounded bight portion to the hook, the same is provided with a camsurface whereby the attachment can be easily operated as will beobvious. In order to provide a seal between the cap and the bottle, Ihave shown the customary sealing gasket 12 which is disposed between thetop of the head B and the disk plate 10 when the cap is attached to thebottle.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such changes fall within thescope of the appended claims.

What I claimis:

1. A bottle cap of the character described comprising a top providedwith a centrally disposed opening, means formed with said top forsecuring the same to a bottle, a disk plate included in said cap andbeing provided with a centrally disposed concavity, a sealing gasketarranged upon the bottom of said disk plate, means for removing said capfrom the bottle and being provided with a hooked end received in saidopening and disposed in said concavity for engagement with the top ofsaid disk plate, a thumb piece for said removing means, means on saidthumb piece for retaining the removing means in normal position, andsaid thumb piece being operable for causingthe terminal of said hookedend to engage the top and remove the cap from the bottle.

2. In a bottle cap, atop hat ing a centrally disposed opening, means forsecuring said top to a bottle, a metallic disk plate pro-. vided with acentrally disposed concavity hooked end formed on one of said arms andbeing provided with a rounded bight por-v tion a thumb piece formed onthe end of the other of said arms, a projection formed on 5 the thumbpiece and adapted to be secured to a cap for securing said removingmeans in normal position, and said hooked end heing operable by thethumb piece for movable engagement with the top and disk plate respectively, in amanner whereby the bight portion acts as a fulcrum andthe terminal of said hooked end engages with the top for removing thecap from the bottle.

In testimony whereof I aifix my signature.

ARTHUR J. EMERY.
